1. A wireless transmitter, comprising:
- a transmitter radio unit working in the millimeter wave frequency band using a directional antenna;
a bidirectional radio unit working in a frequency range different from said transmitter radio unit and using an omnidirectional antenna;
a radio link control unit (RLC) to control said radio units, wherein the radio link control unit is provided to switch, steer or form an antenna beam of the directional antenna of the transmitter radio unit; and
a sounding channel frame generator for sending channel sounding frames transmission messages via the transmitter radio unit to determine channel conditions of an active antenna beam combination and other possible beam combinations with a wireless receiver or a wireless relay, whereinthe bidirectional radio unit is adapted to receive channel measurement values from the wireless receiver or the wireless relay,the channel measurement values are values determined based upon the channel sounding frames transmitted via the transmitter radio unit, andthe radio link control unit switches, steers or forms the antenna beam of the directional antenna of the transmitter radio unit based upon the channel measurement values.
